Why it matters for dental
Dentists and hygienists can now cite a new RCT showing that a 3 % hydrogen-peroxide dentifrice produced measurable whitening in 30 days, giving practices a low-cost, OTC adjunct to in-office or take-home bleaching.
Key points
- Randomized clinical trial (n = 60) published in the Journal of Dentistry, January 2027 issue.
- Study group brushed twice daily with 3 % H₂O₂ dentifrice; shade change was quantified with a spectrophotometer at baseline and 30 days.
- Results are directly applicable to patient counseling on whitening dentifrices versus professional systems.
- Authors are affiliated with Brazilian dental schools, increasing the study’s external validity for general-practice settings.
